I own a gen Breitling Steelfish and I was wondering what makes this watch waterproof up to 2000m / 6600 ft?
There are 3 possible water entry points right (not including the HEV)?
- Crystal
- Crown/ stem
- Case back
So why is this watch waterproof up to 2000m and a replica Submariner for example at most 50m?
Both have steel case, rubber gaskets, pressed crystal and a specific torque needed to fasten the case back and crown...
Any experts on this area?
